Product Details

FineWire™ Iridium Spark Plug by Bosch®. Bosch introduces the new OE Fine Wire Spark Plug family, which consists of Iridium, Double Platinum and Platinum plugs. Built around OE technology, these new lines have an original equipment specific design and are manufactured to be OE equivalent replacements.

During operation, the spark plug is subjected to both wear and fouling and should be replaced at regular intervals. Bosch introduces their latest OE technology to the aftermarket. Built around OE technology, Double Platinum Spark Plugs have an OE specific design and are manufactured to be a direct replacement for OE spark plugs. Thanks to the fine wire design of the center electrode, these plugs deliver better ignitability and guarantee 3x longer service (versus standard Copper plugs) thanks to the Platinum tips on the center and ground electrodes.
